This well hidden court tomb, marked on the OS map as ‘Chambered Grave’, lies 500m north of the portal tomb at Clonlum. The burial gallery, 8.8m in length & aligned N-S. is the best preserved part of the structure. It narrows from 2m in width at the north end to 1m at the south end. A single roof-stone, 2.1m in width, lies out of position at the north end, where the gallery opens out into a forecourt, defined by 3 stones on the west & 2 stones at the east. Very little remains of the cairn which once covered the gallery, but what does remain, suggests that it was rectangular in shape. There is a small rectangular chamber (possibly a later subsidiary burial) set within the north horn of the forecourt. William C. Borlase in his book, ‘The Dolmens of Ireland’ (1897 - Vol. 1 p. 304), notes the two megalithic tombs in this town-land. He writes “ In the Town-land of Clonlum, and Parish of Killevy, about one mile and a quarter E. of the summit of Slieve-Gullion, was a dolmen marked Cromlech in Ord. Surv. Map No. 29 ; also a second not marked”.
